any of the rock? Do you find any layers in the rock are they hori- 

 zontal, vertical, or tilted? Have the rocks changed any during the 

 last six months? If they are wearing away, what agents are active? 



NOTE. In studying distribution of seeds the results of observation should be 

 tabulated. Count number of seeds in each pod or husk and number produced by 

 each plant. 



Relate cultivation to production of seed. Children should very 

 early get the idea of the great interdependencies of the animal, vege- 

 table, and mineral worlds; the great amount of plant food which is 

 locked up in the rocks, the agents which are at work unlocking this 

 plant food and making it available. They should see in the rocks 

 great store houses of energy which must be liberated, and become fa- 

 miliar with the organic and inorganic agents at work.
